I would like to have icons in the fluxbox/blackbox desktop, I tried Nautilus, but since the desktop covers my screen, i wasn't able to launch programs clicking in the desktop, it shows the nautilus desktop menu instead.

so i would like to have icons BUT keep the right click desktop funcionality, i'm currently using ROX running "rox &" in the startup script, but it only shows the home folder in a window... I was thinking about Thunar...

In pcmanfm's preferences just tell it to manage the desktop and show file icons. Then you can drag and drop stuff and manage the desktop wallpaper like in gnome. Also set the option to show menu's when desktop is clicked, so that the flux right click menu shows up.
